RAZOR.

Application filed June 21, 1917. Serial No. 175,999.

To all whom it may concern Be it known that I, lilnrswon'rrr L. Mc-CAIN, a citizen of the United States of America, residing at Detroit,inthe county.

of Wayne and Stateof Michigan, have invented certain new and usefulImprovements in Razors, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to safety razors,

and my invention aims to furnish the usualand well known type of bladehandle with a novel blade holding arm for a single or double edge bladethat may be stropped, honed or sharpened similar to-the ordinaryjack-knife razor. It is in this connection that I aim to provide asafety razor that may be manipulated similar to an ordinary jack-kniferazor, but with a greater degree of safety should the user of my razordesire toequip the blade holding arm with a blade guard.

My invention further aims .to provide a blade holding arm with positiveand reliable.

means, in a manner as hereinafter set forth for holding a detachablesingle or double edge blade, and the holding means is so disposed as tobe readily removed to permit of detachable parts of the razor beingsterilized or thoroughly cleansed.

My invention will be hereinafter described and then claimed, andreference will now be had to the drawing, wherein Figure l is aperspective viewv of the razor;

Fig. 2 is a plan of the blade holding arm,

partly broken away and partly in section;

Fig. 3 is a side elevation of the same, partly broken away and partly insection on the line III-III of Fig. 2;

Fig. 4 is a plan of-the blade holding arm provided with a blade guard;

Fig. 5 is a side elevation of the same, partly broken away and partly insection;

Fig. 6 is a perspective view of a detached single edge blade, showing aslight modification of my invention,

lug.- 7 is a plan of a detached double edge blade, and 7 I Fig. 8 is aplan of a modified form of razor.

In the drawing, the reference numeral 1 generally denotes a razor handlecomposed of opposed ha ndle pieces maintained in spaced relation so asto serve as a guard or pocket for a razor blade. Such a handleSpecification of Letters Patent. I

ordinarily has a blade shank pivoted in the outer end thereof, butinstead of using such a blade, I pivot a blade holding arm 2 in thehandle by studs or trunnions 3 adjacent the Patented am. a, rare.

inner end of the arm 2. The arm 2 is preferably oval in cross sectionand is hollow throughout, somewhat similar to a flattened or oval tube.The outer end of the arm 2 has a lateral slot or bifurcation 3 andintermediate the ends of said arm, the upper face or wall thereof isprovided witha transverse slot 4 and a lateral slot 5 communicating withsaid opening. 1

In the arm 2 is a blade locking rod '6, which for the greater part ofits length, corresponds in cross section to the arm 2, so that saidlocking quickly shifted in and out of said arm. Near the outerend ofsaid'locking rod is a transverse groove 7 and the outer wall of saidgroove is. V-shaped as at 8. The inner rod may be easily and end of thelocking'rod 6 is cylindrical and provided with screwthreads 9 to receivea long knurled nut 10 that abuts the end of the arm 2 to hold the rod ina locked or retracted position. The outer end of the nut 10 has abifurcation or slot 11 in which is pivoted a cross head 12. The crosshead 12 may be housed in the end of the nut so as not to interfere witha swinging movement of the arm 2 relative to the razor handle 1, butwith the cross head 12 at right angles to the axis of the nut 10, thecross head permits a firm gri being obtained upon the nut for rotatingtlib same to firmly anchor the rod 6 within the arm 2. In other words,the

cross head 12 serves functionall as a wrench, and to prevent the nut 10rom becomin the r0 6 may be upset or provided with a head, as at 13which will limit the unscrewing movement of the nut.

A preferred form of blade for the'arm 2 is designated 14 and has asingle sharp edge 15. The opposite edge or back of the blade 14-. iscutaway, as at 16, to provide end tongues 17 and these tongues haveV-shaped notches 18. The formation of the tongues 17 also provides aslot 19 and the manner of placing the blade in engagement with the arm 2is as follows; r

' With the nut 10 unscrewed as far as possible, and the rod 6 pushedforward or in its outermost position in the arm 2, the groove 7 of therod 6 registers with the transverse slot 4 of said arm. The groove 7 isof a less accidentally displaced the end of pulled length than the slot4 of the arm 2, so that the rear wall of the slot 4 will overhang theinner wall of the groove 7, and since the ends of the blade 14 areidentical in design, either end of the blade may be placed in the slot 4and in the groove 7 of the rod 6. The end of the blade may be pushedunder the overhanging wall of the slot 4 and at the same time the outerend of the blade slipped into the lateral slot 3 of the arm 2. The bladeis now in the longitudinal axis of the rod 6 and the inner tongue 17 hasthe notch 18 thereof in contact with the V-shaped wall of the groove 7,consequently the inner end of the blade cannot become laterallydisplaced. The rod 6 can now be retracted or relative to the arm 2 toshift the inner end of the blade 14' into the lateral slot 5 and theouter end of the blade further into the lateral slot 3. As thisoperation takes place, the V-shaped wall 8 of the groove 7 is carriedunder the overhanging portion or'inner' wall of the slot 4, and a wallof the arm 2 enters the slot 19 at the outer end of the blade 14. Thenut 10 can now be rotated into abutting relation with the end of the arm2 and by tightening said nut the blade 14 is firmly held in engagementwith said arm. Before considering a guard that may be used in connectionwith a razor, attention will be had to Figs. 6 and 7 showing otherblades. The blade designated 20 in Fig. 6 is almost the same as theblade 14, except the back edge of the blade has a bar 21 connecting theends there of, and this bar will provide slots 19 to receive walls ofthe arm 2, similar to the slot 19. This type of blade is very rigid andby providing a blade of greater width both of the longitudinal edgesthereof may be sharpened and used. I

In Fig. 7 there is shown a double edged blade 22 having a longitudinalslot 23, and

the end walls of said slot are provided with V-shaped notches 24, saidend walls corresponding to the tongues 17 of the blade 14.

The guard shown 'inFigs. 4 and 5 com prises a convexo-concave plate 25having the longitudinal edges thereof toothed or provided with guards 26for the cutting edges of the blade 27 placed in engagement with the arm2. At the inner end of the plate 25 is a sleeve 28 adapted to fit on thearm 2 and at the outer end of said blade is an inturned lip .29 adaptedto engage in the outer-end of the arm,. between the wall of said-arm andthe blade 27 mounted therein. The plate 25 is placed in engagement withthat side of the arm 2 opposite the transverse slot 4 of said arm, sodoes not interfere with the placing of the blade 27 in position.

ing said arm and a lip A guard along the same lines'may be readily madefor a single blade, as shown in Fig. 1. i

In Fig. 8 a blade holding arm 30 has the outer end thereof cut away, asat 31, to provide clearance for a blade 32 having openings 33 and 34. Onthe outer end of the arm is aslotted lug 35 under which either end ofthe blade may be placed. Slidable in the arm 30 is a rod 36 providedwith a groove 37 to receive the inner end of the blade, and said rodmaybe adjusted, similar to the rod 6, to lock the blade under the lug 35and under the overhanging portion 38 of thea-rm.

What I claim is 1. In a. safety razor, a handle having spaced sidepieces, a blade holding arm pivoted between the side pieces of saidhandle, and adapted to be swung between the side pieces of the handle, ablade in the outer end of said arm, a locking rod in said arm operatableat the inner end thereof andadapted for locking said blade in the outerend of said arm, and a detachable guard on the 3. A safety razorcomprising a blade hold- 1 ing arm provided with lateral slots, ashiftable rod in said arm provided with a groove,

- a blade cut away so that either end thereof may be placed in thegroove of said rod and both ends enter the lateral slots of said arm,

a nut onthe inner end of said rod abutting said arm adapted to shiftsaid rod to lock said blade in engagement with said arm, and a guard forsaid blade having a sleeve to engage said arm and a lip toengage in theend of said arm.

'4. A razor comprising a blade holding arm, a shiftable rod in said arm,a reversible blade held in said arm by said rod, and a guard on said armfor said *blade, said guard having a sleeve atone end thereof embracatthe opposite end thereof extending into said arm.

Intestimony whereof I aflix my signature in presence of two witnesses.
